title: [Angioplasty of the anterior descending artery with abnormal origin: use of a new low-profile catheter balloon. A case report].
abstract: It is possible to perform transluminal coronary angioplasty (TCA) in thin vessels presenting severe obstructions. One of the achievements that made such procedure possible is the development of a new generation of balloon catheters. In this case report the TCA was performed in a very thin left anterior descending artery with an anomalous origin, a quite rare situation that represents a major problem to the traditional dilator system. The catheter used was a Probe (USCI), which differs of the traditional balloons in a number of characteristics. The authors consider the procedure in detail pointing out the advantages of using of the new generations and discuss the impact that newer technological developments will have in enlarging the indications for TCA and improving the results.
